"I wanted a new challenge" - Cross-cultural differences in workers' thoughts about their career changes

by Christian Jarrett in BPS Research Digest

It's not many generations ago that workers expected to have a job for life, most probably one that followed in the footsteps of their father, and his father before that. In many of today's richer societies, it's all different. Longer education and greater individual choice mixed with mergers, take-overs and bankruptcies mean that people's careers are typically punctuated by a series of distinct transitions or chapters. But how do people perceive these transitions and do such perceptions vary bet........ Read more »

Why Are There No Super Whales?

by Dr. M in Deep Sea News

The question is not why are whales big but why are whales not bigger?  The blue whales reached weights of 150 tons prewhaling.  To appreciate how massive a blue whale is, consider it would take 15 school buses, around 10 tons in weight to equal one of these marine mammals.  Why are there no 250 [...]...

More model perils; parametrize this

by The Curious Wavefunction in The Curious Wavefunction

Now here's a very interesting review article that puts some of the pitfalls of models that I have mentioned on these pages in perspective. The article is by Jack Dunitz and his long-time colleague Angelo Gavezzotti. Dunitz is in my opinion one of the finest chemists and technical writers of the last half century and I have learnt a lot from his articles. Two that are on my "top 10" list are his article showing the entropic gain accrued by displacing water molecules in crystals and proteins (a ma........ Read more »

Bogus Science Reporting: Herald-Sun tells you to take your condom off… for her happiness

by Michael Slezak in Good, Bad, and Bogus

The Herald Sun, not exactly known for its high-quality science reporting, has come out with a cracker today about sex and its health benefits. It’s a wonderful mixture of very old news and the sensationalising of some very questionable results. But, its about sex so already in a few short hours its being tweeted like mad and dugg by hundreds of people. Let’s have a quick look at some of the claims in the article whcih range from the boring to the truly irresponsible.

Defending the case for biocentric microbiology

Is it a luxury to “think like a microbe” and to publish blogs such as “Adopt a Microbe“ and books like “The Other End of the Microscope: the Bacteria Tell Their Own Story“ (find it on Google Books)? Is it just about understanding or “getting to know” bacteria, or is it a necessity to be [...]... Read more »

The Fatter We Get, the Less We Seem to Notice

by Travis Saunders, MSc in Obesity Panacea

A significant number of overweight and obese individuals believe their body weight to be appropriate or normal and are satisfied with their body size. Misperception of overweight status is most common among the poor vs wealthy, African Americans vs white Americans, and men vs women. The unfortunate consequence is that overweight individuals who perceive themselves to be of normal weight are less likely to want to lose weight in contrast to overweight individuals with accurate perceptions.

Up to half of drug therapy is ineffective, according to recent statistics. This leaves patients’ diseases untreated, but also places them at risk for side effects and drug interactions.

Huxley and the Pacifier Problem

by Greg Laden in Greg Laden's Blog

The question of pacifiers (and for that matter bottles) arises when there is a new baby. In the case of Huxley, he will be breast milk fed if possible, but that involves bottle feeding at some point. Also, since our society does not practice cross nursing all Western babies go through a risk period when they begin to starve while the mother's milk is not yet in. Sometimes that is a couple of days, sometimes longer.

In any event, the question comes up, do you let a baby anywhere near a nippl........ Read more »

Delay not deviance: brains of children with ADHD mature later than other

by Ed Yong in Not Exactly Rocket Science

This article is reposted from the old Wordpress incarnation of Not Exactly Rocket Science.Attention-deficit hyperactivity disorder is the most common developmental disorder in children, affecting anywhere between 3-5% of the world's school-going population. As the name suggests, kids with ADHD are hyperactive and easily distracted; they are also forgetful and find it difficult to control their own impulses.

While some evidence has suggested that ADHD brains develop in fundamentally different w........ Read more »

A Condominium Plant

by Merry Youle in Small Things Considered

Early in childhood, we learned that the plants and animals around us are discrete entities with definite boundaries. A dog might have fleas, but fleas and dogs are separate and distinct individuals. With our increased familiarity with symbioses—especially those of the obligate sort—have come many instances where "separate" individuals can seemingly survive only as part of a functioning association. Here is yet another example.

For more than twenty-five years, Doyle Mckey, now a professor ........ Read more »

For new brain cells, go to the wild

by Zen Faulkes in NeuroDojo

For a while, people thought that vertebrate brains did not get new neurons throughout life. Songbirds provided one of the first known counterexamples, when it was discovered that some birds generated new neurons, associated with song centers, every year. Later, mammals were discovered to generate new neurons in adulthood, most interestingly in the hippocampus.

The hippocampus is deeply involved in all manner of learning and memory, but particularly spatial learning and memory. The natural hypot........ Read more »
